mass production vs lean production

Dot Product of Vectors and the Resolution of a Vector - It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass a..

It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature, so also it is meaningless to add vector quan..

Apparent Loss of Mass - You must have seen that when substances like wood, wax, coal, oil, etc. are burnt, they seem to disappear, or leave a very small quantity of residue. It looks as if the mass is much lesser. Well, the loss of some mass of these substances is only..

You must have seen that when substances like wood, wax, coal, oil, etc. are burnt, they seem to disappear, or leave a very small quantity of residue. It looks as if the mass is much lesser. Well, the loss of some mass of these substances is only apparent. As per the Law of..

According to this law, during any physical or chemical change, the total mass of the products remains equal to the total mass of the reactants. Law of conservation of mass is also known as 'Law of indestructibility of matte..

. A positron has same mass as an electron but with the opposite charge. So, when an electron and positron are brought together they annihilate and their mass gets converted into energy. The reverse of this process is also possible. It is called as pair production. A ph..

This law was put forth by the French chemist A. Lavoisier (1774). It states that in 'any chemical reaction, the total mass of the system before and after the reaction is the same although its matter can undergo a physical change'. If 'a' grams of A and 'b' grams of B react to give 'c' gr..

; 'a' g, showing that the mass has increased after burning. Here, the mass of the oxygen gas from air required for burning is not measured before the reaction. But the mass of oxygen combined is added in the product. It therefore appears that there is an appa..

Law of Mass Action and Equilibrium Constant - The law of mass action correlates the rate of a chemical reaction and the concentration of the reactants. C.M. Guldberg and P. Waage (1864-67) suggested this relationship. This law states that, at a constant temperature and pressure,..

Mass of the reactants = 10g Mass of the products = 4.6 + 5.6g = 10g Since the mass of the reactants is equal to the mass of the products, the observations are in agreement with the law of conservation of mass..
